the upper measuring claw is rotationally connected with the lower measuring claw through a pin shaft, and the measuring claw head B extends out of the left side surface of the base and is aligned with the measuring claw head A;

one end of the spring is fixedly connected with the upper measuring claw, the other end of the spring is fixedly connected with the vertical plate, and the upper measuring claw and the lower measuring claw are crossed by taking a pin shaft as a cross point under the action of the spring;

and the dial indicator is fixedly connected to the vertical plate in an inserted manner, and the measuring indicator head is positioned on the upper surface of the base and abuts against the front side surface of the upper measuring claw. Through set up intercrossing on the base and measure the claw, measure the claw down, will measure the fixed back of claw down, utilize the pulling force of spring for on measure the claw and use the pivot to rotate as the center, make and measure claw head A and measure claw head B and can part, after measuring claw head A and measuring claw head B and inserting the valve barrel of treating the detection together, can detect through the percentage table and go up measuring claw swing amplitude and measure whether circle runout meets the requirements in the valve barrel, simple and convenient.

Furthermore, a boss A extends forwards from the front side surface of the measuring claw head A, a boss B extends backwards from the rear side surface of the measuring claw head B, and the bosses A and B are the same in size. Through setting up boss A, boss B, increase the measurement position, improve measurement stability.

Furthermore, a limit bolt A is connected to the vertical plate in a threaded manner, and one end of the limit bolt A is connected to one end of the vertical plate in a threaded manner to abut against the upper measuring claw close to the spring side, so that the movement position of the upper measuring claw is limited. Through setting up spacing bolt A, can prevent effectively that the measuring claw amplitude of fluctuation is too big and cause, the percentage table damages.

One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

the utility model discloses simple structure, it is convenient durable, can adjust the position of percentage table as required to the valve barrel that adapts to different models is gone on interior circle and is beated and detect.

Detailed Description

For better understanding of the above technical solutions, the following detailed descriptions will be provided with reference to the drawings and specific embodiments of the specification, and it should be understood that the descriptions of the positions of the "left", "right", "front" and "rear" in the present application are only for convenience of description of the present application and are not intended to limit the technical solutions of the present application.

As shown in fig. 1, the tool for testing the diameter of the oil groove of the valve assembly valve sleeve comprises a base 10, wherein a vertical plate 20 is fixedly connected to the front side surface of the base 10, a lower measuring claw 40 is fixedly connected to the upper surface of the base 10 through a bolt, an upper measuring claw 50 is rotatably connected to the lower measuring claw 40 through a pin 501, a measuring claw head a401 of the lower measuring claw 40 and a measuring claw head B502 of the upper measuring claw 50 both extend out of the left side surface of the base 10, and the extending lengths of the measuring claw head a401 and the measuring claw head B502 are the same.

One end of the spring 60 is fixedly connected to the upper measuring claw 50, the other end of the spring 60 is fixedly connected to the vertical plate 20, and the upper measuring claw 50 and the lower measuring claw 40 are crossed by taking a pin shaft 501 as a cross point under the action of the spring 60;

the dial indicator 30 is further arranged, the dial indicator 30 is fixedly connected to the vertical plate 20 in an inserted mode, and the measuring gauge head is arranged on the upper surface of the base 10 and abuts against the front side face of the upper measuring claw 50.

A boss A402 extends forwards from the front side surface of the measuring claw head A401, a boss B503 extends backwards from the rear side surface of the measuring claw head B502, and the bosses A402 and B503 are the same in size.

The vertical plate 20 is further in threaded connection with a limiting bolt A201, one end of the limiting bolt A201 is in threaded connection with one end of the vertical plate 20 to abut against the upper measuring claw 50 close to the spring 60 side, and the movement position of the upper measuring claw 50 is limited. The dial indicator is prevented from being damaged by overlarge movement amplitude of the upper measuring jaw 50.

The lower measuring claw 40 is fixedly connected to the upper surface of the base 10 through a bolt B403, and a notch avoiding the bolt B403 is formed in the upper measuring claw 50. It can be ensured that the measuring jaw head a401 and the measuring jaw head B502 can be inserted into the valve sleeve together.

In order to effectively fix the dial indicator, a limiting bolt C202 is connected to one side of the vertical plate 20 through a thread, and the end of the limiting bolt C202 is inserted into the mounting hole of the dial indicator 30 and abuts against the dial indicator 30 to limit the position of the dial indicator.

The specific working principle is that when the measuring jaw is used, the measuring jaw is firstly shifted, the measuring jaw head A401 and the measuring jaw head B502 of the valve sleeve standard component to be detected in the batch are simultaneously inserted into an oil groove of the standard component, the dial indicator is installed to the contact front side surface of the measuring head, the dial indicator is adjusted to zero scale, the adjusting limiting bolt A201 is slightly separated from the front side surface of the measuring jaw, the standard component is rotated to change three positions, the standard component is respectively rotated, the runout of the dial indicator is observed, the runout amplitude is smaller than four scales, namely, the calibration is qualified, and if the dial indicator is detected to jump more than six grids at will, the valve sleeve of the same type can be regarded as.
